Lets take for example the "Pitchdetection" example included in the iphone API – how would one set a preffered frequency and pitch and have FMOD detect if the incoming sound is higher or lower than the set preffered

as an example, correct me if im wrong but guitarists need their tunings @ 440hz (or Mhz – idk) and be sure that the "E" note is not more that a few cents out.
